Guake 3.10 has been released with the ability to choose which search engine to use with its “Search on Web” feature, a new pin button to temporarily prevent hiding, and more.
Guake is a drop-down terminal for the GNOME desktop which includes split terminal functionality, session save/restore, support for transparency, and many other features. While it doesn’t support Wayland, it does run using Xwayland, but you’ll need to manually set the hotkey to show/hide Guake.
The application is inspired by the famous Quake console—the terminal stays hidden until you press a key (default is F12). Execute a command, then press the same key again to hide the terminal, going back to your previous task without breaking your workflow.
